There are typically a few common factors that make it hard to enjoy a bit of speed, but unlike most electric scooters on the market, Ausom managed to get just right with their new Leopard DT1 pro scooter. 

Of course, given that you’re in a safe area where it’s legal to get some speed going. Going fast on an electric scooter typically means you start worrying about things like how expensive it’s going to be, braking power, handling, suspension, and battery life. Fortunately in this case Ausom created a powerful 2*1000w motor scooter that’s both fast and feels stable enough to make you want to go faster than 41 mph.

Industrial technology manufacturing company Littelfuse has expanded its range of Ultra Junction X4-Class 200 V Power MOSFETs with low on-state resistance for battery energy storage and power supply applications.

The IXTN400N20X4 and IXTN500N20X4 have around two times higher current ratings and a 63% RDS(on) reduction than existing X4-Class MOSFETs, according to the company, making them ideal for applications where minimizing on-state losses is essential. These include battery energy storage systems (BESS), battery chargers, battery formation, DC/battery load switch, and power supplies.

The high current ratings allow designers to replace multiple low-current-rated devices connected in parallel. The SOT-227B package has screw-mounted terminals that enable rugged and stable mounting.

The Ultra Junction X4-Class Power MOSFETs offer low conduction losses, minimized parallel connection effort, simplified driver design with minimal driver losses, simplified thermal design and increased power density.

The MOSFETs are available in 10 pieces per tube and samples can be requested through authorized Littelfuse distributors worldwide.

“The new devices will allow designers to replace multiple low-current rated devices, connected in parallel, with a single device solution,” said Sachin Shridhar Paradkar, Global Product Marketing Engineer at Littelfuse. “This simplifies gate driver design, improves reliability, improves power density and PCB space utilization.”

Taiwanese electronics manufacturing company Delta Electronics has announced its selection by France-headquartered EV charging network IZIVIA FAST to supply approximately 800 units of its 200 kW DC UFC 200 series EV charger for deployment at McDonald’s restaurant car parks throughout France.

Each charger’s capacity can be divided into two 100 kW units for simultaneous charging of two EVs. The system also features a non-liquid-cooled 400 A high-power CCS cable/connector capable of delivering extra power to a low-charged EV battery.  

IZIVIA CEO Christelle Vives said, “Despite mainland France boasting more than 143,000 publicly accessible charging points, less than 10% provide 150 kW or greater power. IZIVIA FAST, in collaboration with our financial partners Morrison and Crédit Mutuel Impact, aims to bridge this gap. Delta’s UFC 200 ultra-fast charger has proven to be the optimal solution through rigorous testing.”

Improving EV efficiency and safety hinges on an effective Battery Management System (BMS).
For automotive BMS, it’s important to note that the battery pack is not directly connected to the motor.

Instead, it interfaces through relays and fuses. Any disconnection or abnormal connection between these components can lead to unexpected increases in impedance. Since the voltage and current flowing from the battery to the motor are substantial and fluctuate frequently, increased impedance can cause system temperatures to rise and become unstable.

Download this Whitepaper to learn how Hardware-in-the-Loop (HIL) Testbeds can provide a pack voltage and isolation impedance simulator that allows users to easily perform the BMS testing.

NXP Semiconductors has unveiled a new wireless battery management system (BMS) solution with ultra-wideband (UWB) capabilities.

UWB technology uses high-bandwidth pulses instead of a modulated carrier frequency (sinusoidal signal) as used in 2.4 GHz narrowband technologies such as Bluetooth Low Energy. This provides higher resistance to reflections and frequency-selective fading for improved data transfer, according to NXP.

“Wireless communication within battery packs enables robust and reliable transfer of battery cell information such as voltage and temperature measurements from one module to the battery management unit without the need for wiring,” the company explains. “Leveraging wireless solutions minimizes the use of complex wiring harnesses in the battery pack, and reduces the need for error-prone manual effort during production, which makes the assembly of EVs more efficient. The elimination of connectors and wiring between battery cells allows for increased energy density.”

“Our wireless battery management system solution is the industry’s first to include UWB technology,” said Naomi Smit, GM and VP, Battery Management Systems at NXP. “Trimension UWB delivers simple, safe and robust wireless communication within the BMS, outperforming existing narrowband-based solutions.”

NXP’s Ultra-Wideband wireless BMS will be available for OEMs to start evaluation and development in Q2 2025.

Lithium-ion battery manufacturer Electrovaya has received a purchase order valued at approximately $3.5 million for immediate delivery of its batteries from one of its OEM sales channels. The customer is a Fortune 100 e-commerce company, and it will use the batteries to power material-handling EVs in its warehouse operations.

Ontario-based Electrovaya makes batteries and battery components. It has operations in both Canada and New York.

“We are delighted to announce this repeat order to supply this leading Fortune 100 e-commerce customer with our batteries,” said Dr. Jeremy Dang, Vice President of Business Development at Electrovaya. “This customer has been the largest operator of our batteries to date with more than 30 distribution centers. It is a testament to our commitment to providing reliable, safe and long-lasting battery solutions.”

Also this week, Electrovaya secured a direct loan for $50.8 million from the Export-Import Bank of the United States to fund the buildout of its battery manufacturing facility in Jamestown, New York.

Battery materials producer Integrals Power has begun distributing samples of its Lithium Iron Phosphate (LFP) and Lithium Manganese Iron Phosphate (LMFP) battery cathode materials to customers in both Europe and the US. This milestone follows the successful production of these materials at Integrals Power’s UK pilot plant.

The LFP and LMFP cathode materials were fully manufactured in the UK. “This not only underscores Integrals Power’s commitment to advancing domestic manufacturing capabilities but also ensures the highest purity, quality and performance standards,” the company said.

“The fact that these materials were manufactured on our UK pilot line is a proud achievement, and we are excited to see how they perform in the real-world applications of our customers in the EV, battery manufacturing and energy storage sectors,” said Integrals Power founder and CEO Behnam Hormozi.

LFP chemistries are accounting for a growing share of the global battery market, thanks to their safety, long cycle life, low-temperature performance and sustainability benefits. The International Energy Agency reports that in 2023, LFP supplied more than 40 per cent of global EV demand, more than double its share in 2020.

LMFP adds manganese to the mix, which can increase energy density by up to 20% while maintaining the safety and cost-effectiveness of LFP. Integrals Power says it has achieved a manganese content of 80 percent, improving on the 50-70 percent typically found in existing blends. This offers greater performance in EV applications such as EVs, and makes LMFP more competitive with Nickel Manganese Cobalt (NMC) chemistries. (For more information about LFP and LMFP, see our July 2024 feature article on Wildcat Discovery Technologies.)

“By offering these high-quality, UK-manufactured cathode materials, Integrals Power provides its customers with the opportunity to review, test, and ultimately, integrate the materials into their battery and energy storage solutions,” says the company. “This close collaboration will help foster innovations that are essential to meeting the world’s growing demand for clean energy technologies and reduce reliance on China for these strategically important assets.”
